Chapter 1, Problem 12RP

To determine

To prove: In the given diagram, $\angle X\cong \angle Y$

Explanation of Solution

Given information: The following two statements have been given

  $\angle X$ is a right angle

  $\angle Y$ is a right angle

Formula used: If two angles are having same values of measurements, then they are congruent

Proof: From the given information, we can say that $\angle X$ and $\angle Y$ are having same values

Using the formula mentioned, we can say that the two angles $\angle X$ and $\angle Y$ are congruent

Hence proved, that $\angle X\cong \angle Y$
